Kastar Hand Tools 2670 Metric Thread Restorer File 8 Pitches 0.75mm-3.00mm

The Kastar Hand Tools 2670 (Lang Tools) Metric Thread Restorer File is a precision hand tool designed to repair damaged external threads on fasteners of any diameter, both right-hand and left-hand configurations. This specialized file eliminates the need for conventional dies in situations where they cannot be used, providing an efficient alternative for restoring compromised threads.

Eight Metric Pitches: Features eight common metric thread pitches measured in millimeters per thread: 0.75mm, 1.00mm, 1.25mm, 1.50mm, 1.75mm, 2.00mm, 2.50mm, and 3.00mm. This comprehensive range covers the vast majority of metric fasteners found in automotive, motorcycle, marine, RV, and powersports applications.

How It Works: Simply select the proper millimeters per thread pitch that matches your damaged fastener. Position the file over several good threads to establish proper alignment, then work over the damaged area using regular file strokes. The file will reshape and clean the damaged threads, restoring them to their original profile and functionality.

Key Features:

• Highly tempered construction for exceptional strength and durability
• Restores threads without cutting new ones—preserves original thread integrity
• Works on any fastener diameter, right or left-hand threads
• Eliminates the need for costly part replacement
• Packaged in a reusable protective pouch for convenient storage
